STMicroelectronics NV (Geneva, Switzerland) has made an announcement which indicates that it has started delivering samples of its STM32 F3 series of microcontrollers. The products have the functions of a variety of analog peripherals and DSP capability. STM32 F3 series MCU s are syst...

which is small enough to be mounted inside an athlete’s helmet. It can be used to detect ports-related concussions early. It is reported that ports-related concussions have occured in the U.S. over 3.8 million each year. The new MEMS sensor give doctors enough time to protect patient ...

Fabless chip company Dialog Semiconductor plc announced that they had integrated security technology into its SC14453S voice-over-IP processor from startup Intrinsic-ID BV. Dialog (Kirchheim-unter-Teck, Germany) plans to use the Intrinsic-ID technology to ensure that only authenticate...

The circuit is shown as the figure. Usually, the drive tube needs to use transistor (Figure 9013) with higher withstand. When the output voltage increases, VT55's bias increased, then the forward current of light emitting diode in B5 increases, so that the voltage across poles of phot...

AD9101 is built-in the holding capacitor CHOLD, and sample-and-hold is controlled by the CLOCK. According to basic connection diagram, RTN grounds to keep the gain of the amplifier in 4. The noninverting input terminal of ultrafast comparator AD96685BR produced by the Analog Devices I...

The two-speed exhausting fancomposed ofpole-changing adjustable speed motor is widely used in high-rise and underground buildings. Usually it runs at low speed; when the fireisbroke out, itcan be swicthed by manual, fire -place control systems or BAS system to high-speed operationauto...
